Abstract

Cette invention concerne un ensemble filtre qui comprend un cadre de filtre réutilisable (2) ainsi qu'un filtre à auto-espacement, extensible de façon réversible, plissé et interchangeable (8) qui est disposé amovible dans le cadre (2). Le filtre plissé à auto-espacement s'étend uniformément avec un espacement régulier des plis qui permet au filtre d'être facilement monté dans le cadre de filtre réutilisable sans l'aide d'une autre structure d'espacement. Lorsque le filtre est étendu sur la longueur du cadre de filtre, le filtre est sous tension, ce qui permet à la longueur du filtre d'être immédiatement ajustée afin qu'elle corresponde à la longueur du cadre et ce qui permet aux plis d'être alignés sur les nervures correspondantes (32) situées dans le cadre (2).
